The Olann line is constructed of 96% Merino Wool and 4% Lycra. This racerback bra features athletic styling, and a wide elastic band for optimal support and comfort. This merino sports bra offers superior moisture and odor control, excellent support, and all day comfort. We added a touch of Lycra to give this line additional stretch for the perfect fit allowing the garment the move with you without hindering full range of motion. This also allows the garments to conform to a wide variety of body types.
